Sidewalk circle

 
Sidewalk with circle
What were you used for?

It is not clear what this metal ring is for or from.  When the new sidewalk was put in, it was left in place.  Filling in the center makes makes it no longer usable; protruding out of the street makes it foot catching. 
 
Any comments on this scene in the street beneath our feet?

Sidewalk circles

 
hex pattern side walk cover
6 or 7 x 9 or 10 layout

These cast iron sidewalk panels are seen in the street beneath our feet.  The panels have many dings and damages and some edges are sealed with mastic tape.  There is no indication of their original use:  the cover of a sidewalk vault, a coal chute cover, a cover for a stairwell, or to provide a non-slip surface in front of the doorway.
 
 
A closer look reveals some of the details.

Screwed in to place

Each rondel is surrounded by six pointy ovals; those interlock with the ovals of the neighboring rondels.   The panels have alternating columns of 6 or 7 rondels and alternating rows of 9 or 10 rondels, the total being 123.   Screws along the edges hold the panels to the framework.
 
A mysterioso SB CL CO is inscribed in the concrete next to these panels.

Yellow corner

 
lamp post base with yellow over spray
Spreay awaey!

When the parking lot was repaved, it included repainting the lamp post bases yellow.  
 
In the past, that would have been done using a paint brush.  Today, it is done with a sprayer.  Where there once were paint drips, now there is overspray.

Cloudy iridescence

 
iridescence in clouds
Thin clouds of ice crystals

Thin clouds with small and uniformly-shaped ice crystals passing close to the sun diffract the sunlight and produce iridescence.

A train of clouds

The intensity of the irisation increases as the clouds get nearer to the sun.  The clouds on the left are about 10 degrees away from the sun.  As this formation moves to the left, the clouds on the right will soon get to show off their pastel colors.

Three setting suns


The cold clouds of a passing weather front afford the sight of three suns setting.
 
sun digs and sun
Close to the horizon

The sun dogs on either side of the sun are caused by the refraction of the sunlight through the ice crystals in the clouds.   These parhelia are approximately 22 degrees to either side of the sun.  The red is closest to the sun with the blue to the outside.

Contrail in the front

 
clouds with contrail before
There is an airplane there

This twin jet engine aircraft is transiting from the clear skies of a cold front for the cloudier ones of the warm front.

Having entered the warm front, the contrail from the jet plane began getting longer.
